The present invention provides a multi-functional printed circuit board (PCB) for assembling a plurality of components of a power converter in to a single package. The PCB comprises: one or more planar coils respectively formed on one or more PCB layers and aligned with each other for constructing the transformer and the coupler; and a plurality of conducting traces and vias for providing electrical connection among the plurality of components of the power converter.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The multi-functional printed circuit board (PCB) according to claim 2, further comprises a shielding layer interposed between the transformer layer assembly and the coupler layer assembly.
8. The multi-functional printed circuit board (PCB) according to claim 1, wherein the secondary-side controller comprises a secondary band-pass filter configured to filter out noises from the carrier signal transferred by the built-in coupler.
9. The multi-functional printed circuit board (PCB) according to claim 8, wherein the secondary controller further comprises a demodulator configured to receive the carrier signal filtered by the secondary band-pass filter and demodulate the carrier signal to extract the primary control signal.
10. The multi-functional printed circuit board (PCB) according to claim 9, wherein the secondary controller further comprises a secondary driver configured to receive the extracted primary control signal and generate a secondary control signal for controlling the secondary switch based on the extracted primary control signal.
